Dual-display, 5½-digit DMM’s preset buttons ease repetitive testing

Fluke has announced the 8808A DMM (digital multimeter), featuring 5½-digit resolution, multifunction- measurement capability, and a dual display that enables users to simultaneously measure two related parameters, simplifying testing and troubleshooting. The instrument’s front panel includes six programmable set-up buttons that function much like car-radio presets, allowing production operators to quickly follow a test procedure without pushing multiple buttons. A high/ low limit-compare mode with pass/ fail indicators can remove much of the guesswork from testing and can help to eliminate production mistakes. Using the setup buttons to invoke pass/fail tests enhances measurement consistency and thus improves the quality and efficiency of manufacturing test. With measurement functions that include volts, ohms, amperes, and frequency, the meter also meets performance and flexibility requirements for bench meters in R&D and service applications.

The 8808A exhibits a basic dc-voltage maximum error of 0.01% and, according to the manufacturer, is the only meter in its class that features dedicated low-current dcleakage- measurement capability. The unit uses a high-impedance- inputmeasurement circuit to make sensitive low-current measurements without loading the circuit under test; in the 2000- µA range, resolution is 100 nA. The 2x4Ω function uses patented split-terminal jacks that allow users to perform fourwire measurements using only two test leads. The optional two-by-four-wire test leads make possible precise, four-wire, low-resistance measurements on miniature surface-mount components. The US list price is $745.
